■GCWR (Gross Combination Weight Rating)
The  maximum  allowable  gross
combination  weight.  The  gross
combination  weight  is  the  sum
of  the  total  vehicle  weight
(including  the  occupants,  cargo
and  any  optional  equipment
installed on the vehicle) and the
weight of the trailer being towed
(including  the  cargo  in  the
trailer).
■GVWR (Gross Vehicle Weight Rating)
The  maximum  allowable  gross
vehicle  weight.  The  gross  vehi-
cle  weight  is  the  total  weight  of
the  vehicle.  When  towing  a
trailer,  it  is  the  sum  of  the  vehi-
cle  weight  (including  the  occu-
pants,  cargo  and  any  optional
equipment installed on the vehi-
cle) and the tongue weight.
■GAWR (Gross Axle Weight Rating)
The  maximum  allowable  gross
axle  weight.  The  gross  axle
weight  is  the  load  placed  on
each axle (front and rear).

■TWR (Trailer Weight Rating)
The  maximum  allowable  gross
trailer  weight.  The  gross  trailer
weight  is  the  sum  of  the  trailer
weight  and  the  weight  of  the
cargo in the trailer.
TWR  is  calculated  assuming
base  vehicle  with  one  driver,
one  front  passenger,  towing
package (if available), hitch and
hitch systems (if required).
Additional optional equipment, passengers and cargo in the vehicle will
reduce the trailer weight rating so as not to exceed GCWR, GVWR and
GAWR.
If the gross trailer weight exceeds 3000 lb. (1360 kg), it is r ecommended
to use a trailer with 2 or more axles.
■
Unbraked TWR (Unbraked Trailer Weight Rating)

ing a trailer without a trailer ser-
vice brake system.

brakes are required.
● If the gross trailer weight is over 2000 lb. (907 kg), a sway c ontrol
device with sufficient capacity is required.
● If the gross trailer weight is over 5000 lb. (2268 kg), a weigh t distrib-
uting hitch with suffici ent capacity is required.

●A  recommended  tongue  weight  or  kingpin  weight  varies  in  accor-
dance with the types of trailer s or towing as described below.
● To  ensure  the  recommended  values  shown  below,  the  trailer  must
be loaded by referring to t he following instructions.
• Tongue Weight The gross trailer weight should be distributed so that the tong ue
weight  is  9%  to  11%.  (Tongue  We ight/Gross  trailer  weight  x  100
= 9% to 11%)

Tongue Weight
If  using  a  weight  distributing  hi tch  when  towing,  return  the  front
axle to the same weight as b efore the trailer connection.
If  front  axle  weight  cannot  be  measured  directly,  measure  the
front fender height above the front  axle before connection. Adjust
weight distributing hitch torque until front fender is returned  to the
same height as b efore connection.
The  gross  trailer  weight,  gross  axle  weight  and  tongue  weight
can be measured with platform sca les found at a highway weigh-
ing  station,  building  supply  company,  trucking  company,  junk
yard, etc.

■Matching trailer ball height to trailer coupler height
■ Before towing
Check that the following conditions are met:
●Ensure that your vehicle’s tires are properly inflated. ( P. 551)
● Trailer  tires  are  inflated  according  to  the  trailer  manufacture r’s  recommen-
dation.
● All trailer lights work as required by law.
● All lights work each time you connect them.
● The trailer ball is set at the proper height for the coupler on  the trailer.
● The trailer is level when it is hitched.
Do not drive if the trailer is not level, and check for imprope r tongue weight,
overloading, worn suspension, or other possible causes.
● The trailer cargo is securely loaded.
● The  rear  view  mirrors  conform  to  all  applicable  federal,  state/provincial  or
local regulations. If they do not, install rear view mirrors ap propriate for tow-

( P. 211)
No  matter  which  class  of  tow  hitch

the  trailer  ball  setup  must  be  the  proper
height for the coupler on the trailer.
